before i even ask, yes i did run a search but the word tire and maintenance are in sooo many articles and i got tired of combing through them all

now as to the question, i think i may have to rotate my tires but to be honest i dont know much at all about tire maintenance and im sure you all have extensive knowledge on it
basically can you just outline some points (i.e. how to tell you need to rotate or get new tires, rotation patterns, etc)

thanks
